This episode of the FEI Podcast features Thomas DeFabrizio, CFO of Impellam Group Americas, introducing a concept he believes every financial leader needs on their radar: the reaction tax.
What Is the Reaction Tax?
DeFabrizio describes the reaction tax as a cost that never shows up as a single line item on the P&L, yet surfaces everywhere else – margin erosion, rushed pricing decisions, vendor contracts signed under duress, and days sales outstanding that quietly stretches until it can no longer be ignored. “No one books a journal entry” for it, he explains, but companies pay it anyway, often without realizing the true source.
Why Financial Visibility Lags Behind the Business
The root cause, according to DeFabrizio, is visibility that lags behind the speed of the business. Traditional financial systems and ERPs were not built for how quickly markets and technology are now moving, and CFOs who cannot see a problem coming end up reacting to it instead of preventing it. His fix starts with narrowing focus: two or three meaningful KPIs across each of five core categories – growth, profit, value, efficiency, and cash – reviewed on a weekly cadence rather than discovered after the quarter closes.
Aligning KPIs and Compensation
Just as important as the metrics themselves, DeFabrizio says, is making sure everyone in the organization is using the same definitions. Sales pipeline, new business, gross margin – these terms can mean different things to different teams, and that misalignment compounds the reaction tax. He recommends CFOs establish enterprise-wide standard definitions and revisit compensation structures so incentives reward the behaviors the business actually wants, rather than behaviors that look good on paper but erode value.
The AI Factor
DeFabrizio also connects this thinking to the broader shift AI is driving across finance, consulting, and other Member-relevant professions. As AI compresses the time required to deliver results, he argues that pricing models and compensation plans built around time and materials will need to evolve toward outcome-based structures, a shift he sees as an opportunity rather than a threat for financial leaders willing to get ahead of it.
The Bottom Line
His closing challenge to financial leaders: pick the top ten metrics that matter most to your business, put them in front of your team every week, and use them to close decision windows before they close on you.
